After the peace, like many other British naval officers, Hood spent some time in France, and on his return to England was given the command of a sloop, from which he proceeded in succession to various frigates. In the 32-gun fifth-ratefrigateJuno his gallant rescue of some shipwrecked seamen won him a vote of thanks and a sword of honour from the Jamaica assembly.[2]

Early in 1793, after the outbreak of the French Revolutionary Wars, Hood went to the Mediterranean in Juno under his cousin Lord Hood, and distinguished himself by an audacious feat of coolness and seamanship in extricating his vessel from the harbour of Toulon, which he had entered in ignorance of Lord Hood's withdrawal. In 1795, in Aigle, he was put in command of a squadron for the protection of Levantine commerce, and in early 1797 he was given command of the 74-gun ship of the lineZealous, in which he was present at Admiral Horatio Nelson's unsuccessful attack on Santa Cruz de Tenerife. Captain Hood conducted the negotiations which relieved the squadron from the consequences of its failure.[2]

Zealous played an important part at the Battle of the Nile. Her first opponent was put out of action in twelve minutes. Hood immediately engaged other ships, the Guerriere being left powerless to fire a shot.

In command next of the squadron blockading Rochefort, Sir Samuel Hood lost an arm during the Action of 25 September 1806 against a French frigate squadron. Promoted to Rear Admiral a few days after this action, Hood was in 1807 entrusted with the operations against Madeira, which he brought to a successful conclusion.[2]

Present in the roads of A Coruña at the re-embarkation of the army of Sir John Moore after the Battle of A Coruña, Hood thence returned to the Mediterranean, where for two years he commanded a division of the British fleet. In 1811 he became Vice Admiral.[2]
